Fiber Coupling Efficiency calculator
Mode-overlap coupling between Gaussian beam and fiber MFD.
Category: Fiber Optics
Formula: η = (2·w·w₀/(w² + w₀²))²
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Beam waist | w | µm | 5 |
| Fiber MFD | MFD | µm | 10.4 |
Result with the default inputs
- Efficiency: 99.8463 %
- Loss: 0.0067 dB
Open it with your own values: put each input in the address as a parameter, for example /calculators/fiber-coupling-efficiency?w=5. A unit other than the listed one goes in <parameter>_unit.
